With the development of DWDM systems, high isolation channel is necessary to avoid crosstalk. Based on Raysung’s FBG, our athermal DWDM FBG filter features for flat top response and a steep roll down spectral range, which is available in an individual package or combined with multiple filters to form a complete add/drop module. The specifications for Raysung's Athermal DWDM FBG filter are listed in the tables below.
